# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
There was a partial halo CME (angular width about 180 degrees) directed
towards the south, first seen at 03:24 UTC by LASCO C2. This CME originates
from a filament eruption in the southern hemisphere. Since the filament was
located close to the disk center, an ICME may arrive to the Earth on 20
March.
